POWER MEASUREMENT OF MECHANICAL LOSSES IN EXPERIMENTAL RECIPROCATING AIR COMPRESSOR IMPACT OF PISTON GROUP

Abstract

Power losses in the reciprocating piston air compressors are mainly engaged to overcome friction. Based on the large number of research on internal combustion engines have confirmed that the mechanical losses of piston group parts make up most of the losses related to friction in the engines. Therefore, their reduction has a direct effect on reducing fuel consumption. For research purposes, the sliding surface of the piston and cylinder of aluminium alloy are tribological optimized. In addition to tribological, have carried out and testing of experimental reciprocating compressor on the bench, in the laboratory for engines and compressors in Faculty of Engineering in Kragujevac. Optimization has confirmed by measurement of mechanical losses related to specific effective work with tribological optimized different pairs of piston groups.
